Bug#556: hp-toolbox segfaults when started in x2go MATE session
by erik.devriendt＠telenet.be 15 May '15

15 May '15

Package: nx-libs Version: 3.5.0.27 Distribution: Linux Mint 17 64-bit. hp-toolbox segfaults when started in a x2go MATE session. hp-toolbox is a python script, part of the hplip-gui package in Linux Mint 17. After unsetting the LD_LIBRARY_PATH environment variable, hp-toolbox starts without segfaulting. (hp-toolbox started in a shell in a terminal window).

Bug#123: Fwd: Message with no Package: tag cannot be processed! (nxagent package missing dependancy on Scientific Linux)
by Vincent Gerris 15 May '15

15 May '15

Package: nxagent Hi folks This is aretry of my bug report. Why not just use a bugtracker like trac? I did have a line with Package: . Well, this is another try, the previous content: I use X2Go on Scientific Linux, which is very similar to CentOS. After a recent regular update I encountered a dependancy issue: Error: Package: nxagent-3.5.0.17-3.1.x86_64 (X11_RemoteDesktop_x2go) Requires: xorg-x11-fonts-core The mentioned package seems to only exist on Suse. I use the X2xo repo to install packages, this is the content of my repo file: [X11_RemoteDesktop_x2go] name=X2go - after NoMachine ditched the open version (RHEL_6) type=rpm-md baseurl= http://download.opensuse.org/repositories/X11:/RemoteDesktop:/x2go/RHEL_6/ gpgcheck=1 gpgkey= http://download.opensuse.org/repositories/X11:/RemoteDesktop:/x2go/RHEL_6/r… enabled=1 Is there an issue with the built? Kind regards, Vincent

Bug#271: nx-3.5.0.20 breaks FreeNX on RPM based system
by Mike Gabriel 15 May '15

Package: nx-libs Version: 3.5.0.20 Tag: rpm-packages Hi Jan, 23:31 < masc88> hello. nx-3.5.0.20 appears to introduce corruption within server side session file and communication protocol 23:32 < masc88> on session resume in conjunction with freenx. is this a known issue? 23:33 < masc88> I had to downgrade to nx-3.5.0.17 to stabilize resuming of sessions obviously there is a problem with FreeNX / X2Go if nx-3.5.0.20 is installed. I assume that the installation is on an RPM based system (because the .deb packages do not have a package named nx).

Bug#637: nx-libs improvements
by Michael DePaulo 15 May '15

15 May '15

Hi Andre. I know it's been a while since you replied to this bug. However, the X2Go project and the Arctica Project have started doing major code cleanups to nx-libs on the new 3.6.x branch. Many of those code cleanups are big because they involve making nx-libs using the system version of X11-related libraries rather than nx-libs bundling its own (horribly outdated) version of those libraries. Those changes will improve compatibility with some X11 apps, but not Qt5 apps. After those code cleanups are complete, we will look into either rebasing nx-libs against the latest X.org, or backporting features such as newer RandR and XInput2 to nx-libs. In either case, Qt5 apps will become compatible. There is no ETA though. Code and issues are located here: https://github.com/ArcticaProject/nx-libs/tree/3.6.x Code is also located here: http://code.x2go.org/gitweb?p=nx-libs.git;a=shortlog;h=refs/heads/3.6.x -Mike#2

We're encountering the same problem here. gnome-control-center (gnome-control-center:28288): Gdk-WARNING **: The program 'gnome-control-center' received an X Window System error. This probably reflects a bug in the program. The error was 'BadLength (poly request too large or internal Xlib length erro'. (Details: serial 153 error_code 16 request_code 147 minor_code 1) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) lsb_release -a No LSB modules are available.

FYI: I updated the Fedora Rawhide mock files onjenkins
by Michael DePaulo 31 Mar '15

31 Mar '15

On Japsand, which Jenkins builds on, I updated the mock files (/etc/mock/*.cfg) for Fedora Rawhide to their mock 1.2.7-1 versions: https://apps.fedoraproject.org/packages/mock/changelog/ One of the differences is that the rawhide RPMs now have "fc23" instead of "fc22" in their names. I started rebuilding the Rawhide packages through the Jenkins WebGUI. I intend to finish doing so tonight. -Mike#2
